Schedule C Line 6: What Counts as "Other Income" for Freelancers (2026)

Published: June 12, 2026 · Reading time: 6 min

TL;DR: Line 6 catches business income that isn't a sale: recovered bad debts, interest on client notes and receivables, scrap sales, state fuel tax refunds, business prizes and awards, and Section 179 recapture when equipment's business use drops to 50% or less. Your actual revenue goes on Line 1; credit card rewards are a price reduction, not income; loans and collected sales tax stay off the form entirely. Everything on Line 6 flows into Line 7 gross income and ultimately into self-employment tax — there's no SE-tax-free lane inside Schedule C.

Most freelancers breeze past Line 6 with a zero — correctly. But the year a client pays interest on a late balance, a state refunds your fuel taxes, or your business-use percentage on an expensed laptop slips, Line 6 is suddenly the right answer to "where does this go?" Here's the complete map.

Where Line 6 Sits in Part I

Schedule C Part I builds gross income in seven lines: gross receipts (Line 1), returns and allowances (Line 2), cost of goods sold (Line 4), gross profit (Line 5), other income (Line 6), and the total on Line 7. Line 6 exists so business income that isn't a sale still gets counted — without distorting the Line 1 figure that the IRS matches against your 1099-NECs and 1099-Ks.

What Belongs on Line 6

Recovered bad debts

If you're an accrual-basis freelancer who wrote off an unpaid invoice in a prior year and the client later pays, the recovery is income in the year received — Line 6. (Cash-basis filers never deducted the loss, so a late payment is just ordinary Line 1 income when it arrives.)

Interest on notes and accounts receivable

Late-payment interest a client pays under your contract, or interest on a payment plan you extended for a big project, is business interest income — Line 6, not Schedule B. Interest on your personal savings stays on Schedule B and out of self-employment income.

Scrap, salvage, and byproduct sales

A welder selling scrap metal, a woodworker selling sawdust and offcuts, a screen printer selling misprints by the pound — sales of leftover materials and byproducts that aren't your actual product line land on Line 6. (Selling a depreciated asset like a retired camera is different: that's Form 4797 territory, not Line 6.)

Fuel tax refunds and credits

State gasoline or fuel tax refunds received in 2026 go on Line 6 if the fuel was deducted as a business expense. Same for the federal fuel tax credit (Form 4136) claimed on last year's return — the credit repaid you for a tax you deducted, so it comes back as income.

Business prizes and awards

An industry award with a cash prize, a vendor's contest for top resellers, a design competition win — if it's connected to your trade or business, it's Line 6 income (and yes, it's subject to SE tax, unlike a purely personal prize reported as other income on Schedule 1).

Section 179 and listed-property recapture

Expense a laptop 100% under Section 179 or bonus depreciation, then let business use slide to 50% or less before the recovery period ends, and Form 4797 computes a recapture amount that reports as other income right back on the schedule that took the deduction — Line 6. A simple usage log on dual-use gear is the cheap insurance.

What Does Not Belong on Line 6

Client revenue — that's Line 1, full stop, even odd one-off gigs
Credit card rewards and cash-back — price reductions that net down the expense, not income
Loans and lines of credit — borrowed money was never income (the interest you pay is Line 16)
Sales tax collected — you're holding the state's money; keep it out of income and out of expenses
Refundable security deposits — not income until forfeited
Personal interest, dividends, and hobby winnings — Schedule B / Schedule 1, where they escape SE tax legitimately
Income from a genuinely separate business — that gets its own Schedule C, not a Line 6 entry on this one

The Tax Effect: Same Pot, Same SE Tax

Line 6 isn't a softer-taxed category. It joins Line 7 gross income, expenses come off in Part II, and the Line 31 net profit flows to Schedule SE for the 15.3% self-employment tax — then into your quarterly estimate math. The reason to get Line 1 vs Line 6 right isn't the rate; it's that Line 1 should reconcile cleanly with your 1099s so the IRS's document-matching computers stay quiet.

Documentation for Each Entry

Line 6 amounts tend to arrive as one-off paper: a state refund notice, a contest award letter, a contract clause charging late interest. Treat each like a receipt — capture it, date it, note what it was. A clean records system that holds the income paper trail alongside categorized expenses is what makes a Line 6 entry a thirty-second answer in an audit instead of a mystery.

Frequently Asked Questions

What goes on Schedule C Line 6?

Line 6 is for business income that doesn't come from your primary sales or services: bad debts you previously wrote off and later recovered, interest on notes and accounts receivable from clients, scrap or salvage sales, state gasoline or fuel tax refunds received during the year, the fuel tax credit claimed on a prior-year return, prizes and awards connected to your trade or business, and recapture amounts such as Section 179 recapture when equipment's business use drops to 50% or less. Your normal client revenue belongs on Line 1, not Line 6.

What's the difference between Line 1 gross receipts and Line 6 other income?

Line 1 is revenue from the thing your business actually does — client invoices, product sales, platform payouts. Line 6 is business income arising from operating the business that isn't itself a sale: a refund of fuel taxes you deducted, interest a client paid on a late balance under a written agreement, an industry award with a cash prize. Both end up in gross income on Line 7 and both are subject to self-employment tax, so misplacing an amount between them rarely changes the tax — but matching 1099s to Line 1 keeps IRS document-matching clean.

Do credit card rewards or cash-back go on Line 6?

Generally no. Rewards earned on purchases are treated as a price reduction, not income — the correct handling is to reduce the deducted expense (or simply deduct the net cost), not to report the rebate as other income. The exception is a reward that isn't tied to spending, such as a pure sign-up bonus with no purchase requirement, which can be taxable income. Loans, security deposits you must return, and sales tax you collect for the state also stay off Line 6 — they were never your income.

Is Line 6 income subject to self-employment tax?

Yes. Line 6 feeds Line 7 (gross income), and after expenses, the net profit on Line 31 flows to Schedule SE. There's no separate, SE-tax-free lane inside Schedule C — if an amount belongs on Line 6 because it arose from your trade or business, it's part of the same net profit that gets hit with the 15.3% self-employment tax. Income that is genuinely not business-related — say, interest on your personal savings — belongs on Schedule B instead and escapes SE tax for that reason, not because of which Schedule C line it's on.

What is Section 179 recapture and why does it land on Line 6?

If you expensed equipment under Section 179 and its business use later drops to 50% or less before the end of its depreciation life, you must recapture part of the deduction — effectively giving back the difference between what you expensed and the depreciation you would have been allowed. The recapture is computed on Form 4797 and reported as other income on the same schedule where you originally took the deduction, which for a freelancer means Schedule C Line 6. Keeping a usage log for dual-use gear like cameras and laptops is what protects you here.
